Thanks everybody.

Hi,

As a experiment/learning experience I got a Gigabyte H110M-A motherboard (https://www.gigabyte.com/Motherboard/GA-H110M-A-rev-10#ov) for running a "lab" with only 2 GPUs.

Should it work? ie: I guess as long as my PSU is big enough and I have the PCIe risers, any motherboard with PCIe connectors can be used.

Is that correct? thanks.

So... do I connect one rail (cable from PSU) to each riser/video card combination?

Hi,

I have a mini-rig for experiements.

Two GPUs (RX570) with a small motherboard (Gigabyte H110M-A) and risers.

I have these risers: https://www.amazon.ca/gp/product/B076KLJR2Y/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1.

My PSU is a Corsair 850i. It comes setup for multi-rail operation by default (it can be changed to single rail).

So, how should I connect this (power)? more importantly, how should I  NOT connect this? (ie: what would be unsafe/wrong).

My plan is to use using PCIe cable and plug the two risers in it (use the 6 PIN power plug in the risers), and use individual PCIe cables for each video card. Is there a way to test the risers before actually plugging the video cards in them?

My understanding is that that should be safe (all power is coming from the same PSU, even though they are different rails).

Please advise. Thanks.
